10A buck regulator provides 45% area reduction
1 min read
Intersil has announced its newest 10A integrated FET synchronous buck regulator, which it claims provides up to 45% total area reduction over alternative devices.
The ISL95210 is a single output buck regulator that requires only four external components. Intersil's says its patented R4 control architecture provides 'exceptional' transient response with no external compensation components. Potential applications include point of load power supplies for computing and networking infrastructure equipment.
An external d/a converter is programmed by two external pins and allows designers to select from nine different regulator output voltages. Several digital control signals provide flexibility to programme switching frequency, switching mode, output voltage margining and a daisy chained power good output. According to Intersil, the ISL95210 also includes comprehensive internal protection for overvoltage, undervoltage, overcurrent and overtemperature conditions.
Features include 10A continuous output current; 2.97 to 5.5V input voltage range; up to 95% efficiency; 0.6% output voltage accuracy (over temperature); transient response without external compensation components; and full power operating in a 90°C environment without airflow.
